SELFQSEALING BOTTLE.

SPECIFICATION forming part of Letters Patent No. 545,982, dated September 10, 1895.

' Application filed December 31,1894. Serial No. 533,383. (No model.)

To all whom it may concern;

Be it known that I, ERNEST SCHORR, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in a Safety or Self-Sealing Bottle; and I de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to ithe acconhp'anying drawings, which form a part of this specification.

Myinventionis designed to provide a safety or self-sealing bottle and one which will infallibly disclose an attempt to refill the bottle after its original contents have been with drawn therefrom.

To these endsmy invention consists of the construction, combination, and arrangement of devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in which' Figure 1 is a vertical section on the line 1 1, Fig. at. Fig. 2 is a vertical section through the neck of the bottle on the line 2 2, Fig. 3. Fig. 3 is a horizontal section on the line 3 3, Fig. 1. Fig. 4 is a horizontal section on the line 4 4, Fig. 1, looking upward toward the top of the bottle. Fig. 5 is a detail view of the indicator-tubes.

In carrying out my invention I provide the neck A of the bottle with or locate therein two sets of vertically-extended loops, B and B indicating the two sets of loops, which I prefer to arrange on opposite sides of the neck therein, as indicated. I do not limit myself to any particular number of loops in each set, and their size will depend upon the kind of liquid to be contained in the bottle. The two sets of loops are preferably independent the one of the other. One set of loops-as, for instance, the set B- -opens into the upper end of the bottle, as indicated at b, the lower end of the loop terminating toward the lower end of the neck' of the bottle. The lower end of the opposite loop is carried downward toward the base of the bottle, as indicated at b, the upper extremities of bothlo'ops' terminating toward the upper end of the neck of the bottle, as indicated at b and h I have shown the neck of the bottle constructed independently of the body A thereof and united thereto, as at A The neck may be joined to the body of the bottle in any suitable manner. Within the neck I form an air-tight chamber 0. To form the said chamber, I locate a diaphragm O toward the lower end of the neck and an additional diaphragm 0 toward the upper end of the neck, the central portion of the upper dia phragm 0 being preferably countersunk, as

indicated at C The upper extremities b and b of the loops B B open through the diaphragm 0 preferably within said countersunk portion 0 thereof.

The lower extremities of the two sets of loops B B open into the body of the bottle below the diaphragm O, the one extremity opening into said body immediately beneath said diaphragm, as at b, the other extremity, as above explained, being carried downward to the base of the bottle. The main portions of the two sets of loops B B are located at the sides of the air-chamber O. I prefer that the loops intermediate the extremities thereof should project above the upper extremities b? cated at 0) through which the contents of the bottle'rnay discharge. E is an ordinary cork or stopper. Within the air chamber 0, I also locate indicator tubes or channels F and F, one of said indicator-tubes, as the tube F, being more fully shown in Fig. 2. These tubes or channels I prefer to arrange in a zigzag or winding form across the neck of the bottle. The upper extremity of one of said indicator tubes or channels, as of the tube F, opens upward through the countersunk portion of the diaphragm 0 adjacent to the open endsof the extremities b b of the loops B B. The lower end of the tube opening upward through the diaphragm O is closed. The upper end of the opposite tube, as the tube F, is closed at the upper end, as'atf, Fig. 1, the lower end thereof opening through the diaphragm O, as at f, Fig. 5. i

The operation of the device so far described is as follows: The bottle is filled before the neck A is engaged with the body A. thereof.

per E and turning up the bottle in the cus tomary manner to discharge its contents the liquid within the bottle will enter one set of loops at the point b and discharge at the opposite extremity of the corresponding set of loops. At the same time air will enter the upper extremity of the opposite set of loops and be discharged into the base of the bottle, as at the point I). In this manner the contents of the bottle may readily be discharged. I prefer to locate the upper extremities b b of said sets of loops B B below the upper face of the diaphragm C and below the upper ends of the loops intermediate the extremities thereof, so that any attempt to refill the bottle while the bottle is in an upright position will cause the liquid to enter the extremities b b of both sets of loops B B, in consequence of which the air within the bottle, not being permitted to escape, will effectually prevent the en trance of any liquid into the body of the bottle, so that there can be no liability or possibility of refilling the bottle when in an upright position and exposed to atmospheric pressure. Should any attempt be made to exhaust the air within the bottle, the air would not only be exhausted from the bottle and the loops B B, but would also inevitably be exhausted from the tubes or channels F F, by reason of which any liquid attempted to be put into the body of the bottle would fill the indicatortubes F F and permanently remain therein, thereby effectually and infallibly disclosing the fraud, as the liquid would appear in said indicator-tubes and could not be discharged therefrom. These tubes I prefer to make frail, as of thin glass, so that they may be easily broken by undue pressure from without or from within. The air-chamber 0 may contain, if desired, a few drops of water, so that any attempt to heat the neck of the bot tle would cause the air within said chamber, and especially the vapor contained therein, should a few drops of water be placed in said chamber, to expand, and thereby create pressure, which would break the indicator-tubes. I prefer, also, to locate a suitable diaphragm H above the upper end of the tube F to prevent any tampering with said tube. It will thus be apparent that the loops B B afford the desired atmospheric pressure required to effect the free discharge of the liquid in the bottle, while at the same time they serve to suspend any fluid attempted to be passed therethrough into the bottle and prevent its entrance into the bottle. The indicator-tubes F F also serve infallibly to detect the attempt to refill the bottle in consequence of the fluid entering therein. The fragile nature of the indicator-tubes, moreover, enables them to be readily ruptured should any attempt be made to force fluid into the bottle, while the air-tight chamber 0 would frustrate any attempt by. the use of heat to drive out the liquid in the indicator-tubes, as such an attempt would be sure to break the indicator-tubes and might explode the neck itself.

The various diaphragms above described also prevent tampering with the orifices of the various tubes.

It will be understood that should an attempt be made to refill the bottle by exhausting the air therefrom one of the indicatortubes, as the tube'F, would be filled. Then should an attempt be made to empty the tube F by exhaustion the other tube, as the tube F, would be filled, and in this manner the fraud would be infallibly manifested. I prefer to coil the tube F at its upper end and to coil the tube F at its lower end, as shown.
